MEANS FOR CONTROLLING A FUEL-0IL SUPPLY.

To all whom it may concern Be it known that I, CHARLES I. MANEE, a citizen of the United States, and resident of the borough of Manhattan, city, county, and State of New York, have invented certain new Means for Controlling a Fuel-Oil Supply, of which the following is a specification.

My invention relates to means for controlling the supply of fuel oil to a stove or to any similar device that uses fuel oil, for the production of heat or light. I have found that such devices operate more satisfactorily when the fuel is retained at a constant and predetermined level and when the supply may be admitted automatically and when required. In addition to the advantage of regulating the supply and holding it at a constant level the device, the subject of my invention, provides means for continuing the supply so that the device shall require but little or no attention, and so that its use may be continuous through a great length of time.

In constructing my device I have adapted it for use with any ordinary oil burning apparatus and the device may be inserted and placed in operative position without change in the construction or any of the principal features thereof.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form a part of this specification, in which the figure shows in elevation, partly in section a completed device in operable position.

Similar reference numerals indicate like parts in all the figures where they appear.

In the lower portion of the drawing I have shown an ordinary oil stove having a fuel tank 1, and a plurality of burners 2 and 3 which support an ordinary grid 4:.

At 5 I show a cap which may be the ordinary screw cap entered into the top of the tank and which is removed for filling in the ordinary way.

With the use of my device a pipe 6 of any suitable length and preferably of metal is screw-threaded into the cap 5 and extends upward with or without pipe fitting 7 and to be entered into a supply tank 8. The pipe 6 is the means by which the fuel is conducted from a supply tank of any suitable size and through which the fuel is allowed to flow by gravity into the tank or reservoi o th l mp, nd I and useful Improvements in Specification of Letters Patent.

Application filed September 18, 1915.

Serial No. 51,484.

provide a funnel opening 9 having a cover 10, by means of which the supply tank 8 may be filled.

Secured to the inner side of the cap 5 and extending downward into the tank or reservoir 1 is a tubular member 11 communicating with the pipe 6 and having a port 12 in one of its side walls. Arranged within the tubular member 11 and movable therein is a piston 13 connected to which is a rod 14 extending downward into the reservoir 1 and receiving an adjustable block 15. Secured in the block 15 is an angled rod 16 the outer or free end of which receives a float 17.

It will be noted that the gravity pressure of the oil in the pipe 6 is received on the piston 13 and this piston should fit within the cylindrical or tubular member 11 with sufficient accuracy to prevent the oil from passing beyond or around the piston 13; when however the fuel in the tank 1 is lowered to a sufiicient extent the float 17 will drop allowing the piston 13 to pass downward and uncover the perforation 12, at which time oil will be free to pass from the tank 8 into the tank or reservoir 1. The flow of oil will continue until the float 17 causes the piston to again close the passage through the perforation 12. If however, the fuel seeps around the piston 13 and the tank 1 receives more oil than originally intended the float 17 will be raised to a greater extent and the disk 1.8 which may be a leather disk and which should be secured onto the piston 13 will be caused to impinge upon the inner end of the pipe 6 to effectually close the passage through the pipe forbidding the entrance of fuel into the tank 1 until the level in the tank has been reduced or lowered.

I have shown the rod 16 bent or off-set. I do this so that the fuel level in the tank 1 may be predetermined as by removing the adjustable member 15 from the rod 14 and reversing it and the float 17, the float may be caused to assume the position shown by the dotted lines 19 under which conditions the fuel level would be maintained at a lower point. The extent of the off-set in the rod 16 may be changed at will. I may provide for a higher or lower fuel level by increasing the amount of the off-set in this red 16. I may find it possible to omit the disk 18 depending entirely upon the piston 13 to effectually prevent the flow of oil into the. tank 1 when no flow is desired, and although other IILOdifiCfltlOIlS may be made within the scope of the appended claims I prefer the whole as shown and described.

Having carefully and fully described my invention what I claim and desire to secure by Letters Patent is 1. A device of the character described having areservoir, a cylinder having a port and arranged within said reservoir, a supply pipe entering said cylinder, a piston in said cylinder adapted to open and close said port, a float adjustably connected to and operating said piston and a valve upon'said piston and adapted to engage upon the end of said pipe to check the flow through said pipe and said cylinder.

2. A device having a reservoir, a screwthreaded plug entering said reservoir, a pipe connecting said plug and a Source of supply, a cylinder secured to said plug and communicating with said pipe, a piston within said cylinder, a float connected to said piston and an off-set and reversible means connecting said float and piston and CHARLES ISAAC MANEE.
